Recall the digital signature birthday attack discussed in Section 5.4. Suppose we modify the hashing scheme as follows: Given a message M that Alice wants to sign, she randomly selects R, then she computes the signature as S = [h(M, R)]A\ice, and sends (M, R, S) to Bob. Does this prevent the attack? Why or why not?
